The Composition of Soybean Lecithin

Soy lecithin is extracted from soybean oil. It is used as a food and drug additive (often as an emulsifier).

In 1981, the Journal of the American Oil Chemists’ Society published a study of the “Composition of Soybean Lecithin”.  The primary finding was, “Commercial soybean lecithin is a complex mixture containing approximately 65-75% phospholipids together with triglycerides and smaller amounts of other substances. The major phospholipids include phosphatidylcholine, phosphatidylethanolamine and inositol-containing phosphatides. Other substances reported include carbohydrates, pigments, sterols and sterol glycosides.”

The carbohydrates they found did not include any of the FODMAP chain —  “Fermentable, Oligo-, Di-, Mono-saccharides and Polyols”.   They found:  phosphatidylcholine, phosphatidylethanolamine,  inositol phosphatides, other phosphatides, soybean oil, sterols and free carbohydrates.  The full article can be accessed through the link below.
